“…An example of antimicrobial agents added to the alginate-based edible coating is vanilla essential oils. Utama, N.A., et al, study result shows that the addition of green grass jelly and vanilla essential oil on the application of alginate-based edible coating can be conducted to hinder bacterial growth and prolong the shelf-life of water apple fruit [15].…”

Some plants whose leaves can be made into green grass jelly are Cyclea barbata (Cincau rambat bulu), Premna oblongata Miq (Cincau perdu), and Cocculus orbiculatus (Cincau jelly). However, the percentage of the content contained in each plant leaf is not necessarily the same. This study aims to determine the percentage of chlorophyll, flavonoids, dietary fibre, and water content from these three fresh leaves planted by researchers in Semarang. The analysis of chlorophyll content using spectrophotometry method with a 663 nm and 645 nm wavelength. The analysis of flavonoid content using the spectrophotometry method with a 420 nm wavelength. The study of dietary fibre content using the multienzyme method. And the analysis of water content using the heating method. Cyclea barbata leaves have the highest chlorophyll (9.806%) and flavonoids (0.1054%) content of all, while Premna oblongata Miq leaves have the highest water content (79.3370%) and dietary fibre (12.5125%) content of all.

The present work presents the results of the production of vanillin-doped alginate bio lm. Alginate dressings are already a therapeutic reality, but they act only by maintaining the appropriate environment for healing. With the intention of improving their properties, the incorporation of vanillin was proposed due to its antioxidant and antimicrobial potential. Different bio lms were produced employing experiment planning through response surface analysis, which allowed determining the best region for a medium value of solubility and high degree of intumescence. This region refers to values above 0.07 g of CaCl 2 and concentrations above 0.024 g of vanillin, triggering a solubility between 25% and 30% and a degree of intumescence above 100% and with xed values of alginate (0.85 g). As for the optimization of the process, the Normal Boundary Intersection (NBI) method was able to analyze concave regions, predicting the optimal points and generating the Pareto chart with equidistant limits The antimicrobial test allowed the observation of antimicrobial activity against Escherichia coli and Pseudomonas aeruginosa microorganisms from the bio lms, as well as a solution of vanillin with calcium chloride and glycerol obtaining a halo of inhibition only in the presence of vanillin. Thermal analysis of thermogravimetry and differential exploratory calorimetry showed that the material has thermal stability, in the temperature range ideal for application as a biomaterial, for example as biocuratives.

Edible coating is a thin layer that can be made of several materials, one of which is polysaccharides, such as alginates, carrageenan, agar, chitin, chitosan, pectin, starch, cellulose derivatives, and gums. The application of food products with edible coatings has been widely carried out and has been proven to improve quality and extend the shelf life of the product. Antibacterial agent can be added to improve the performance of edible coating. This study was aimed to explore the potential of lemongrass essential oil as an antibacterial agent in alginate based antibacterial edible coating solutions, especially against pathogenic bacteria. Edible coating is made of alginate powder, modified cassava flour (Mocaf), beeswax, glycerol and antibacterial agent. The additional levels of lemongrass essential oil into edible coating formula were 0.25, 1.50 and 0.75%. The antibacterial activity of the edible coating solution produced was tested against Escherichia coli, Staphylococcus aureus, Salmonella, and Pseudomonas aeruginosa by employing a disk diffusion testing method. Antibacterial agents used in previous studies to develop alginate-based antibacterial edible coatings and potential applications of the developed alginate-based edible coatings incorporated with lemongrass essential oil were identified by browsing through the internet. The results showed that various antibacterial agents have been explored to improve the performance of alginate based edible coatings. An antibacterial activity study exhibited that the highest antibacterial activity was found in the edible coating with the addition of 0.50% lemongrass essential oil, except for S. aureus at the addition level of 0.75%. This study suggests that the addition of lemongrass essential oil for the manufacture of alginate based edible coating solution is 0.50%. The potential uses of edible coatings made from alginate with the addition of lemongrass essential oil are to coat various animal and plant based food products.
